CIExposureAdjust

Adjusts the exposure setting for an image similar to the way you control exposure for a camera when you change the F-stop.

• -inputEV <number> : The amount to adjust the exposure of the image by. The larger the value, the brighter the exposure. [Default 0.5]
• -inputImage <image> : The image to use as an input image. For filters that also use a background image, this is the foreground image.
